MonthlyMaintenanceWindow

UMIACS takes a monthly maintenance window to patch and reboot our hosts. This provides a way to ensure security updates are installed and activated on the numerous different platforms and appliances that we maintain.

The window is calculated each month by adding 9 days to Microsoft's Patch Tuesday. This allows us to marshal patches released that month from Microsoft, Red Hat, and our other vendors and have enough time to get our systems prepared to reboot for that month's window.

The window is always going to be on a Thursday from 8pm-12am. A tentative list of maintenance windows for 2017 is as follows with the upcoming window in bold.

• September 21st 2017
• October 19th 2017
• November: TBD, any emergency patching in November, will be scheduled based on need, otherwise November will be skipped this year.
• December 21st 2017
